Let's divide 897269 by 25
The aim is to understand the frequency of 25 in 897269.

Step 1:
When dividing 8 by 25, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 25

Going ahead to step 2:
When dividing 89 by 25, we get 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 75 from 89 and we're left with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 25

Let's proceed to step 3:
The number 25 fits into 147 5 times, leaving a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 125 from 147 to get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 25

Advancing to step 4:
25 goes into 222 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 358.0
The remainder is 22 after subtracting 200 from 222.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 25

Moving on to step 5:
If we divide 226 by 25, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3589.0
If we subtract 225 from 226, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 25

Advancing to step 6:
19 divided by 25 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 35890.0
The remainder is 19 after subtracting 0 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
25 goes into 190 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 35890.7
If we take 175 away from 190, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
When dividing 150 by 25, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 35890.76
If we take 150 away from 150, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35890.76
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35890.76
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 35890.76 and a remainder of 0.0.
